Estimate by PAC is $2-3k for 3 days work. I'm guessing the high end due to slooowness of the initial charging of each cell that is required will take a lot of time and go beyond 3 days.
If you got a BMS back and have a bunch of undeletable errors, it's most likely other hardware failures, not the BMS's fault. The DC-DC converter takes others with it when it goes down. Look for used parts, there are some around. Mercedes won;t sell internal parts unfortunately.Hi
I have a 2015 Smart ED, I bought from a dealer in Centralia,WA. I have it at home in Kapowsin,WA on high blocks to get the HV battery out. It is a little tricky to get the battery out, I use my motorcycle stand from Harbor Freight. On the back side is the HV plug and a Hose with a quick connect, on the driver side in the back is the Communication plug, on the front are two coolant lines. The Battery weights 400lbs . When the battery is removed from the car, remove all nut and screws. drill out the rivets and break the seal. A blow dryer helps and a flat screwdriver. Pull the cover strait up and on the left side is the BMS.
I send my BMS to Lithuania per EQpassion via USPS for about $70. FEDEX was $280. USPS only track within the US. I got it back after 6 weeks and the Brick error P18051C has been deleted for good, but there are 21 other error still active, some are just in Memory. My AUTEL scanner says it cannot delete the errors.
I build a charger with part I had. I does not monitor the battery. i check the battery over time if it has equal charge and increased the voltage slowly. Now the battery is at 70% according to the gauge on my dashboard that is 360Volt DC. The fuse in the HV Battery is over 200A that more power that PSE delivers to my house lol. Still HV to Workshop is displayed. I am looking for extra stuff.
hi there, I have a same issue with my 2014 smart . did you get yours fixed? help pleaseI still think it's bricked -- charged the 12V completely and it still refuses to charge the HV battery. What a piece of junk. Mercedes service was completely unhelpful, of course. They just want to sell me a $10k battery and don't actually do repairs.
